ORS 708A.510: Right of institution to setoff; amount.

Without qualifying any other statutory or common law right to setoff or lien and subject to any contractual provision, if a party to a multiple-party account is indebted to an insured institution, the insured institution has a right to setoff against the account in which the party has or had a present right of withdrawal immediately before the party’s death. The amount of the account that is subject to setoff is the proportion to which the debtor is, or was immediately before the death of the debtor, beneficially entitled and, in the absence of proof of net contributions, to an equal share with all parties that have present rights of withdrawal.
